ENGINE-STARTER Specification of Letters Patent.

Application filed December 14, 1917. Serial No. 207,026.

.the accompanying drawings.

The invention relates to engine starters and has particular reference tothe construction by means of which the starting motor may beconveniently mounted in relation to the engine casing. To this end theinvention comprisesthe novel construction as hereinafter set forth.

7 In the drawings:

Figure 1 is a plan view of a portion of the engine casing including thehousing for the transmission gearing;

Fig. 2 is an end elevation thereof.

In the construction of power units for motor vehicles it is usual tomount the starter on some portion of the engine cas ing so as tomaintain the same in fixed relation to the mechanism which is driven instarting. \Vhere the driven member is on the fly-wheel, which is usuallyassociated with the clutch and transmission mechanism, the startingmotor must 'be mounted in relation to these parts. lVith the presentconstruction I have devised a simple mounting and one in which thestarting motor is accessibly positioned, by forming a flange on thehousing for the transmission and flywheel and bolting the motor thereto.This has the advantage that the face of the flange on which the motor ismounted may be conveniently machined at the same time that the housingis set for the performance of other machining operations thereon.

In detail, A is the engine housing and B is the housing for thetransmission gearing which is secured to the housing A by the flange G.aperturcd at D for clampingbolts.

The housiig B. is fashioned to receive the fly-wheel ,which as shown isprovided with a peripheral gear F for engaging the pinion G of thestarting motor H. The

mounting for this motor is formed by an ei'ctension I at one point inthe flange U, which forms a bearing for the end flange J of the startingmotor case, said'flange being apertured to register with apertures inthe flange I and secured thereto by bolts Whexr the housing B is thussecured the driving shaft of the starting motor will extend parallel tothe axis of the main crankshaft and adjacent to the gear F, so that thepinion Gr may be moved into or out of mesh with-the gear by slidinglongitudinally on said shaft. The shaft and pinion will be housed in aportion of the housing B for the transmission gearing.

The construction being as described, the starting motor may be mountedor disengaged by the simple operation of securing or loosening the boltsK, and when mounted it is securely fastened in fixed relation to thefly-wheel and gear-wheel F.

What I claim as my invention is:

1. In an engine, the combination with the engine casing and an adjacentcasing for housing a fly-wheel and transmission gearing, of a flange 0nthe latter casing for securing the same to the engine casing, and astarting motor mounted on an extension of said flange.

- 2. The combination with an engine casing and an adjacent casing forhousing the flywheel and transmission gearing, of a flange on the lattercasing for securing the same to the engine casing provided with anextension at one point, a starting motor having a flanged end mounted onthe extended flange of said housing, and means for securing saidstarting motor to'said flange.

In testimony whereof I aflix my signature.

FRANK E. WATTS.
